Product overview This 28 kW heat exchanger is built from Stainless Steel 304 for reliable pool heating. Designed for saltwater use and waterproof construction, it provides efficient thermal transfer using the Countercurrent Principle. The unit supports a flow rate of 150 L/min or 9 m3/h and features a ReversePort layout for flexible plumbing. Its compact design allows Vertical and Horizontal installation, making it suitable for whirlpool and solar connection applications. Key benefits Efficient heating performance: 28 kW capacity and Countercurrent Principle deliver effective heat transfer between the heat source and pool water without mixing fluids. Saltwater compatible and waterproof: Stainless Steel 304 construction and waterresistant design resist corrosion from salt pools and harsh environments. Flexible flow and plumbing: Rated for 150 L/min (9 m3/h) and equipped with ReversePort to simplify pipe routing and installation orientation. Spacesaving installation: Compact footprint supports both Vertical and Horizontal mounting to fit technical rooms, pool cabinets, or tight spaces. Versatile integration: Works with solar loops, boilers, heat pumps, and pool circulation systems to provide consistent heating for pools, whirlpools, and spas. What it does This heat exchanger transfers heat from a primary heating circuit to pool water in a closed loop. The Countercurrent Principle means the hot and cold fluids flow in opposite directions for improved temperature transfer. ReversePort configuration provides added flexibility for inlet and outlet connections without changing unit performance. Important specifications Heating capacity: 28 kW Material: Stainless Steel 304 Flow rate: 150 L/min (9 m3/h) Suitable medium: Pool water, including saltwater applications Design features: Countercurrent Principle, ReversePort plumbing layout Installation orientation: Vertical or Horizontal Form factor: Compact, designed for tight installations and integration with whirlpool and solar systems Installation and compatibility notes Match pump and circulation flow to the rated 150 L/min to achieve expected thermal performance. ReversePort layout allows easier connection to existing piping and reduces the need for additional fittings. Can be connected to solar thermal collectors, heat pumps, or boilers as the heat source; maintain separate closed circuits to avoid crosscontamination. Suitable for indoor and protected outdoor installations where the heat exchanger is shielded from direct weather exposure. Use scenarios Solarassisted pool heating: Install the exchanger between a solar thermal loop and the pool circulation. The Countercurrent Principle maximizes heat transfer from solarheated fluid to pool water while keeping fluids separate. Whirlpool or spa heating: Compact size and Vertical or Horizontal mounting let the unit fit into equipment bays for whirlpools or spas, maintaining comfortable bathing temperatures with saltwater compatibility. Backup boiler or heat pump integration: Use the heat exchanger to transfer heat from a boiler or heat pump to the pool circuit, ensuring isolated systems and simplified maintenance. Why choose this model This heat exchanger combines a proven material, Stainless Steel 304, with an efficient Countercurrent Principle and a practical ReversePort layout. It is sized for moderate to large pool circulation at 150 L/min and is built to perform with saltwater systems. The compact and flexible installation options make it a practical choice for pool and whirlpool heating where space and corrosion resistance matter. Technical reminder Ensure hydraulic compatibility and proper flow control when integrating into existing pool systems. Follow local plumbing codes and good practice for isolation valves, filters, and air separation to protect system components and maintain performance.
